The first control valve is moved by operation of the first flush control. The second control valve and the first water supply valve move by operation of the first control valve. When the first control valve is closed pressurized water is applied to the second control valve and the first water supply valve to maintain them closed. When the first control valve is open the water pressure applied to the second control valve and the first water supply valve is reduced causing them to open. When the first water supply valve is closed pressurized water is prevented from being delivered to a toilet bowl and when open pressurized water is delivered to a bottom jet of the toilet bowl. ##

input of the toilet bowl. ### Claim 6 (depends on 1) The water control system as claimed in claim 1 comprising a first diaphragm pump operatively associated with the first control valve and having a first and a second diaphragm position, when the first control valve is in its closed configuration the first diaphragm pump is in its first diaphragm position, when the first control valve moves from its closed to its open configuration the first diaphragm pump is moved to its second diaphragm position thereby transferring water from its first diaphragm position into its second diaphragm position, when the first control valve moves from its open to its closed configuration the first diaphragm pump moves from its second diaphragm position to its first diaphragm position thereby forcing cleaning solution from a cleaning solution tank to be delivered to a rim of the toilet bowl. ### Claim 7 (depends on 6) The water control system as claimed in claim 6 comprising a second diaphragm pump operatively associated with the second control valve and having a first and second diaphragm position, when the second control valve is in its closed configuration the second diaphragm pump is in its first diaphragm position, when the second control valve moves from its close to its open configuration the second diaphragm pump is moved from its first to its second diaphragm position thereby transferring water from its first diaphragm position into its second diaphragm position, when the second control valve moves from its open to its closed configuration the second diaphragm pump moves from its second diaphragm position to its first diaphragm position thereby forcing cleaning solution from the cleaning solution tank to be delivered to the rim of the toilet bowl. ### Claim 8 (depends on 4) The water control system as claimed in claim 4 wherein the first water supply valve, the second control valve, and the second water supply valve are housed together in a central housing. ###
